Grigor Dimitrov will chase his first grass court title at Queen's Club after dispatching top seed Stanislas Wawrinka in a one-sided Aegon Championships semi-final.

The Bulgarian dislodged Swiss world number three Wawrinka 6-2 6-4, to close in on his third tour crown of 2014.

The 23-year-old world number 13 has already scooped silverware in Acapulco and Bucharest this year, and will chase a third in Sunday's final.

Both players showed impressive enterprise on the grass, but it was Dimitrov's superior net-court craft that guided him home in straight sets.

Dimitrov has had girlfriend and French Open champion Maria Sharapova in London watching on in support this week, and the Russian world number five has proved a good luck charm.

Wawrinka proved Dimitrov's first real test of any calibre at Queen's, after eighth-seed Alexandr Dolgopolov withdrew from Friday's quarter-final with thigh trouble - and he emerged with plenty of credit.

A performance of some guile helped him past in-form Wawrinka though, who had only dropped one set en route to the final.

Feliciano Lopez outgunned wily Czech Radek Stepanek to book his place in the final alongside Dimitrov.
